The human cervical spine consisted of 33 vertebrae, including the cervical, thoracic, lumbar, sacral, and coccygeal vertebrae.
Inside the spine was a substance called the spinal cord, which was composed of countless neurons.
One end of the spinal cord connected to the brain, while the other connected to the limbs and the rest of the body, forming an unobstructed bridge for the transmission of human nerve signals.
Therefore, once a problem occurred in the spine, it usually meant that the spinal cord had been damaged. The commands sent by the brain could not reach the corresponding parts of the body, resulting in paralysis.
According to conventional medical methods available to date, nerve damage remained clinically irreversible. Only the various stem cell treatments still in the laboratory occasionally brought good news.
In essence, the STEM chip did not cure paralysis. Instead, it served as a medium, connecting the two ends of severed nerves and allowing signals transmitted by the brain to cross the break and continue onward.
Therefore, based on the STEM chip's functions, it could only achieve its greatest effect when implanted in the cervical spine.
The reason cervical implantation was necessary was actually just as shown in the movies: at the cervical spine, the chip could intercept the nerve signals sent by the host's brain and thereby control the host's body.
Of course, the chip could also be placed in the host's lumbar spine. In that case, however, it could probably control only the host's lower body.
At that moment, in one of the research institute's operating rooms, Samuel nervously leaned against the observation window. Through the cold glass, he stared blankly at the person on the operating table.
She was a seventeen- or eighteen-year-old girl with a face full of freckles and a head of soft, brilliant blond
